Since 2004, we were dedicated to hydropower, as an effective and ecological energetic source and to recreation of the importance of this source in Slovak energetical spectrum. After several successful projects and the resultant managing service, we have widened our focus on developing additional tools to maximize hydroelectric power plants effectiveness. After launching our own hydropower plant cleaning system, we moved to the next journey. Our future goal is to develop a solution that would enable more effective and therefore more ecological usage of provided electric energy. The solution we are working on, Second-Life Battery Storage Systems (SeLiS) is one of the IPCEI (Important projects of common European interest) projects and will offer a battery storage system from recycled batteries for wide range of clients with different types of usage. We do believe that continues utilization of ecological sources is the right direction for the future of energy segment.
